Distant Galaxy Spectra - II

The spectrum is now Hanning (triangle) smoothed along the wavelength axis, to allow features to stand out from the noise. What spectral features are present in the spectrum?

Distant Galaxy Spectra - B

The night sky line emission ([OH lines]) has been subtracted across the slit, to allow the galaxy spectrum to be better resolved. What is the source of each feature? Do you see any characteristic patterns? Are there features which are present and features which are missing? Are they all real?
